KIDS TRIVIA

Detailed explanation-1: -Uplift of the Colorado Plateau was a key step in the eventual formation of Grand Canyon . The action of plate tectonics lifted the rocks high and flat, creating a plateau through which the Colorado River could cut down.

Detailed explanation-2: -The Grand Canyon, in the U.S. state of Arizona, is a product of tectonic uplift. It has been carved, over millions of years, as the Colorado River cuts down through the Colorado Plateau. The Grand Canyon is between 5 million and 70 million years old. A canyon is a deep, narrow valley with steep sides.

Detailed explanation-3: -Scientists estimate the canyon may have formed 5 to 6 million years ago when the Colorado River began to cut a channel through layers of rock. Humans have inhabited the area in and around the canyon since the last Ice Age. The first Europeans to reach the Grand Canyon were Spanish explorers in the 1540s.

Detailed explanation-4: -From its origin to its mouth in the Gulf of California, many hands have claimed the Colorado waters for such purposes as irrigation and water supply. The Colorado River within the boundaries of Grand Canyon National Park drains an area of approximately 41, 070 square miles.

Detailed explanation-5: -This incredible formation was carved over millions of years by the Colorado River. The canyon itself has formed much more recently than the deposition of rock layers, only about five million years ago (as opposed to the rocks, the youngest of which are a little less than 300 million years old).
